[Elecraft] K3s and DTF on RTTY

[Juhani Viitala]

HI!

On RTTY/AFSK I can't use Dual Tone Filter (DTF). My RTTY program is 
TrueTTY and it uses USB for RTTY and that's why I must use DATA-REV.  My 
K3s config is AFSK > DATA-REV > PITCH 1275-170. Everything works fine 
when using "normal" filttering but if I turn APF to DTF everything 
dissapear in waterfall. I have tried to change PITCH but no help. What 
am I doing wrong?
